There’s a simple way to measure the speed of sound. It’s low tech and unimpressive, but you get to blast an air horn. How many times can you say that you’re using one for science and not sheer ...

Researchers have devised a revolutionary new technique for measuring the microscopic elasticity of materials. Known as SRAS, the technology works by measuring the speed of sound across the material's ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

Researchers have measured the speed of sound in pure iron under pressures similar to those that exist at the Earth’s inner core boundary. The result suggests that this region of the core may be ...

Scientists from the CMS collaboration at CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to understanding how matter behaved in the very early ...

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second ...
